signalling: Sets the signaling type for following channel definitions.
These parameters should match the channels as defined in
/etc/zaptel.conf. Correct choices are based on the hardware available
Asterisk will fail to start if a channel signaling definition is incorrect or unworkable, if the statements do not match zaptel.conf, or if the
device is not present or properly configured.
Legal values for signalling are:

fxo_ks: FXO Kewlstart signalling. Used to signal an FXS device within the system, which would normally drive a handset or other station device. Kewlstart is Loopstart with Disconnect Supervision.
fxs_ks: The opposite side of fxo_ks. To signal an internal (or T1 connected) FXO device.
fxo_gs: Use FXO groundstart signalling.
fxs_gs: Use FXS groundstart signalling.
fxo_ls: Use FXO loopstart signalling
fxs_ls: Use FXS loopstart signalling

1. In /etc/directory modify the zaptel. Conf file
2. Identify the numerical position on FXO port on your analog card
fxsks=l
loadzone=us
defaultzone=us
3. Establishing port type and signaling fxsks=l
4. Determining your time zone
loadzone=us
defaultzone=us
5. Load the driver for the card like specific driver to make it work. Driver can be pciradi, torisa, wcfxo, wctdm etc
6. Command "Ispci" identifies your Digium or Sangoma card type
7. Installing the driver with the following commands
modprobe zaptel
modprobe wctdrn24xxp
modprobe wcusb
8. Execute the command "# /sbin/ztcfg vv" to validate if configuration is successful.
